問(wen)：我(wo)在電腦上毗連麥(mai)克風后呈現了良(liang)多樂音，包(bao)含CPU電扇、硬(ying)盤(pan)、光驅讀盤(pan)的樂音都能傳出來，叨教若何(he)能力(li)處理這(zhe)個題目？

答： 處理該題目(mu)的(de)(de)(de)(de)(de)體例以下(xia)：(1)若是(shi)簡直聽(ting)(ting)到的(de)(de)(de)(de)(de)是(shi)硬盤(pan)(pan)、光驅和(he)(he)(he)CPU電(dian)(dian)(dian)扇(shan)帶來的(de)(de)(de)(de)(de)噪(zao)聲(sheng)(sheng)，則能(neng)夠是(shi)主板(ban)、電(dian)(dian)(dian)源(yuan)的(de)(de)(de)(de)(de)濾波電(dian)(dian)(dian)路機能(neng)不(bu)(bu)良，沒(mei)法濾除硬盤(pan)(pan)、光驅和(he)(he)(he)CPU電(dian)(dian)(dian)扇(shan)所發生(sheng)的(de)(de)(de)(de)(de)攪擾旌(jing)旗燈號(hao)(hao)(hao)形成(cheng)的(de)(de)(de)(de)(de)影響。延長IDE電(dian)(dian)(dian)纜線(xian)(xian)(xian)和(he)(he)(he)CPU電(dian)(dian)(dian)扇(shan)電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)都可(ke)削減(jian)響應裝備(bei)的(de)(de)(de)(de)(de)影響，也可(ke)換(huan)個電(dian)(dian)(dian)源(yuan)嘗嘗。 (2)麥(mai)克風與聲(sheng)(sheng)卡(ka)的(de)(de)(de)(de)(de)連線(xian)(xian)(xian)未利用(yong)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)或(huo)(huo)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)接(jie)地(di)(di)(di)不(bu)(bu)良，外界高(gao)頻攪擾旌(jing)旗燈號(hao)(hao)(hao)由麥(mai)克風輸(shu)出串入均會(hui)引發噪(zao)聲(sheng)(sheng)。在這類環境(jing)下(xia)，拔(ba)掉麥(mai)克風后，噪(zao)聲(sheng)(sheng)該當(dang)消(xiao)逝。若是(shi)是(shi)接(jie)上(shang)麥(mai)克風帶來的(de)(de)(de)(de)(de)影響，未利用(yong)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)的(de)(de)(de)(de)(de)需換(huan)用(yong)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)：如利用(yong)了屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)，則用(yong)萬(wan)用(yong)表查(cha)抄屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)外層的(de)(de)(de)(de)(de)金屬屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)層是(shi)不(bu)(bu)是(shi)與機箱(xiang)(xiang)接(jie)通，解除接(jie)地(di)(di)(di)不(bu)(bu)良的(de)(de)(de)(de)(de)影響。另外，從聲(sheng)(sheng)卡(ka)到有源(yuan)音箱(xiang)(xiang)的(de)(de)(de)(de)(de)旌(jing)旗燈號(hao)(hao)(hao)線(xian)(xian)(xian)也應利用(yong)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)線(xian)(xian)(xian)并接(jie)地(di)(di)(di)。 (3)在“起(qi)頭”菜單當(dang)選擇“附(fu)件”中的(de)(de)(de)(de)(de)“繪圖”法式翻開一幅(fu)高(gao)彩圖形，剪下(xia)一塊，用(yong)鼠(shu)標疾速(su)拖動，如能(neng)聽(ting)(ting)到拖動時的(de)(de)(de)(de)(de)“刷(shua)刷(shua)”聲(sheng)(sheng)，則是(shi)因為機內主板(ban)、顯(xian)現(xian)(xian)卡(ka)發生(sheng)的(de)(de)(de)(de)(de)高(gao)頻輻射的(de)(de)(de)(de)(de)影響而至，將(jiang)(jiang)聲(sheng)(sheng)卡(ka)插(cha)在闊別(bie)顯(xian)現(xian)(xian)卡(ka)的(de)(de)(de)(de)(de)擴大槽中，用(yong)鋁制屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)罩將(jiang)(jiang)聲(sheng)(sheng)卡(ka)屏(ping)(ping)(ping)障(zhang)(zhang)(zhang)并接(jie)地(di)(di)(di)(拉尋箱(xiang)(xiang))，就可(ke)以削減(jian)高(gao)頻輻射的(de)(de)(de)(de)(de)影響。 (4)查(cha)抄一下(xia)音箱(xiang)(xiang)和(he)(he)(he)聲(sheng)(sheng)卡(ka)的(de)(de)(de)(de)(de)連線(xian)(xian)(xian)，不(bu)(bu)要將(jiang)(jiang)Line Out和(he)(he)(he)SPK連線(xian)(xian)(xian)插(cha)倒置。Line Out 插(cha)座輸(shu)出未經(jing)縮(suo)小(xiao)的(de)(de)(de)(de)(de)音頻旌(jing)旗燈號(hao)(hao)(hao)(高(gao)阻(zu))，用(yong)于接(jie)有源(yuan)音箱(xiang)(xiang)或(huo)(huo)縮(suo)小(xiao)器；SPK插(cha)座輸(shu)出經(jing)聲(sheng)(sheng)卡(ka)內置縮(suo)小(xiao)器縮(suo)小(xiao)的(de)(de)(de)(de)(de)音頻旌(jing)旗燈號(hao)(hao)(hao)(低阻(zu))，用(yong)于接(jie)無(wu)源(yuan)音箱(xiang)(xiang)或(huo)(huo)喇(la)叭(ba)。若是(shi)毛病地(di)(di)(di)將(jiang)(jiang)有源(yuan)音箱(xiang)(xiang)的(de)(de)(de)(de)(de)輸(shu)出線(xian)(xian)(xian)插(cha)在SPK插(cha)座上(shang)，因為阻(zu)抗不(bu)(bu)婚配、音頻旌(jing)旗燈號(hao)(hao)(hao)(包含噪(zao)聲(sheng)(sheng)旌(jing)旗燈號(hao)(hao)(hao))經(jing)兩次縮(suo)小(xiao)帶來的(de)(de)(de)(de)(de)失真(zhen)均會(hui)發生(sheng)噪(zao)聲(sheng)(sheng)。 (5)改換(huan)品質(zhi)更好的(de)(de)(de)(de)(de)聲(sheng)(sheng)卡(ka)。
